This approach to debating strikes me as exemplifying everything bad that I learned in high school policy debate. Specifically, it seems to me like debate distilled down to a status competition, with arguments as soldiers and the goal being for your side to win. For status competitions, signaling of intellectual ability, and demonstrating your blue or green allegiance, this works well. What it does not sound like, to me, is someone who is seeking the truth for herself. If you engaged in a debate with someone of lesser rhetorical skill, but who was also correct on an issue where you were incorrect (perhaps not even the main subject of the debate, but a small portion), would you notice? Would you give their argument proper attention, attempt to fix your opponent's arguments, and learn from the result? Or would you simply be happy that you had out-debated them, supported all your soldiers, killed the enemy soldiers, and "won" the debate? Beware the prodigy of refutation.
